3. A single phase input (loss of L2)

Amps.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Machine won’t produce full output.

 

 

1. Input voltage may be too low,

 

 

 

 

 

 

 

 

 

 

 

limiting output capability of the

 

 

 

 

 

 

 

 

 

 

 

power source. Make certain that

 

 

 

 

 

 

 

 

 

 

 

the input voltage is proper,

 

 

 

 

 

 

 

 

 

 

 

according to the Rating Plate

 

 

 

 

 

 

 

 

 

 

 

located on the rear of the

 

 

 

 

 

 

 

 

 

 

 

machine.

 

 

 

 

 

 

 

 

 

 

 

2. Input may be “single phased”.

 

 

 

If all recommended possible areas

 

 

 

 

 

 

 

Make certain the input voltage is
